WNT1 - Re-Programming Connect Control Unit and Central Computer (PCM) (Cluster 37)
(Workshop Campaign)
Important:
CRITICAL WARNING -This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order.
Model Year:
2022
Model Line:
Panamera (971)
Concerns:
Connect control unit and central computer (PCM)
Cause:
Optimized software is available for the Connect control unit and central computer (PCM)
control unit.
Measures:
•
•
•
Depending on the booked scope, the Connect control unit and the central computer (PCM) control
unit must be re-programmed with the latest PIWIS Tester software version.
Minimum requirement: Version 42.000.030
Replace Owner's Manual in the on-board folder in the vehicle with an updated version.
Checklist:
For better clarity, a checklist was created as an aid for carrying out the campaign. This does not replace
TI.
The checklist does not have to be attached to the job line in PCSS.
For checklist, see  Technical Information 'Checklist'
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Re-programming Connect control unit and central computer (PCM) (Cluster 37)
Information
If a deviation in the integration test is still indicated despite programming being carried out, this must be
repeated. If the deviation persists, contact Technical Support.
Work
Procedure:
Information
Before starting programming, particular attention must be paid to the following:
•
The charger must be switched off and on once; the battery charger display must be off before
starting it again, because the battery charger automatically switches to trickle charging after
5 hours (default setting in the charger).
•
Set charge voltage to 14.6 volts.
•
Operate in charging mode.
•
Vehicles with a PVTS contract must be activated for Service mode.
•
The PIWIS Tester must not be charged using the cigarette lighter!
1
Create Vehicle Analysis Log (VAL) using the PIWIS Tester. Mark the vehicle analysis log you have just
created with the attribute “Pre-VAL” and after carrying out the campaign, return it using the PIWIS
Tester.
If Scope 1 is assigned to the vehicle, continue with Step 2.
If Scope 6 is assigned to the vehicle, continue with Step 3.

Program Connect control unit.
If Scope 6 is assigned to the vehicle, continue with Step 4.

Overview of PCM update
Information
The central computer (PCM) software update is performed using a SD storage card. The software
version that is specific to each region must be downloaded using the software tool PiUS (Porsche
integrated Update Service) and must be installed on a blank SD storage card.
Pay particular attention to the following:
•
For this PCM software update, a USB storage medium must be used.
•
To use the software tool, one blank or re-writable USB storage medium is required for each individual software.
•
The software available in PiUS must only be used in accordance with the instructions provided in a
Technical Information published for this purpose.
The software listed here may only be used for the measure described here. Damage to the central
computer cannot be ruled out if the software is used on other vehicles.
You will find further information on installation and use for the PiUS software tool in the PPN portal under
*PiUS (Porsche integrated Update Service) goes live*.
